PRESS FOR EXPRYESSING olL FROM COTTON AND OTHER SEEDS,

SPECIFICATION forming part of Letters Patent No. 354,673, dated December 21, 1886.

Application filed May 25, 1686.

To all whom it may concern.-

Be it known that I, CHRISTIAN BAUMGA R- TEN, of Schulenburg, in the county of Fayette and State of Texas, have invented new and useful Improvements in Presses for Expressing Oil from Cotton and other Seeds, of which the following is a full, clear, and exact description.

This invention relates to hydraulic presses for extracting the oil from cotton and other seeds, and is more particularly designed to be applied to hydraulic-presses constructed, so far asthe ram, cylinder, and packing and guiding devices for the ram are concerned, substantially as described in my Letters Patent for a cotton-baling'press, No. 302,880, dated July 29, 1884. I g

The invention consists in certain novel constructions and combination of the pressingplates with each other and the ram of the press, and in means for operating said plates inindependent series, whereby great efficiency is obtained, and the plates, which are guttered or grooved, may be readily cleaned, substantially as hereinafter shown and described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section of a press embodying my invention. Fig. 2 is a horizontal section upon the line main Fig. 1. Fig. 3 is a horizontal section upon the line g y in Fig. 1; Fig. 4, a vertical section through one of the pressing-plates upon the line 2 zin Fig. 2, and Fig. 5 a plan iew of'a screen used on the pressing-plates.

Ais the vertical cylinder of the press; B, its hollow ram; 0, the pipe by which the water or other fluid is supplied to the cylinder from the pump or pumps used to work the press b, the recessed collar on the upper end of the cylinder containing apacking, c, and d the packing ring or gland.

D D are the uprights, rods, or guides, up and down which the pressing-plates, that are suitably recessed in their sides for the purpose, move, said rods or guides, which are turnedat their lower ends, passing through holes in the top planed plate or collar of the cylinder, that is also provided with holes for wrapped in cloth) carried by the plates.

the bolts e, which hold down the stuffingbox gland d.

E is the cap or upper plate of the press, against which the thrust is made, and which is secured on top of the rods D D'by nuts f.

G G are the pressing-plates, which are generally of similar construction, and with the lower one of which the top of the ram B is connected. The other pressing-platesare built up in sets of two, three, or more, the several plates in each set being loosely connected by bolts g with each other, so that the lower plate or plates of each set are suspended from the upper plate,- and are free to move upward.

when pressure is applied independently of each other, but are kept at their" proper distances apart for charging with the material to be com pressed when the ram is down.

' To carry out this action or arrangement, the

uprights or bars D are each provided with studs h, corresponding, each horizontal series, with the number of sets of pressing-plates G, so that the upper plate of each set of plates rests when lowered upon its respective studs h greater or lesser number of pressing-plates may be used in the press at any one time, according to the requirement of the Work.

Each pressing-plate G is cast in a single piece, then planed smooth and grooved, as at k, to allow the oil to escape whenpressure is applied from the material or seeds (usually The grooves k are out clean out to one edge of the plates, and are made of increasing depth toward their outer ends, to allow the oil to run down and from the plates into a trough or vessel set to receive it. p The upper faces of the pressingplates are constructed with raised ribs Z at the inner ends and for aportion of the sides of the series of grooves, to form, in connection with a lower rib or strip, 1, areceptacle or space forthe material to be compressed. This extra rib or strip Z is riveted or otherwise secured to its place after the plateshave been otherwise finished, so as notto interfere with the cutting of the grooves to the deliveryedge of the plates. Within the receptacle or space formed by the ribs 1 Z, and over the grooves k,a piece of closelyavoven wire-c1oth, H, bound on its edges with sheet metal m, is placed, to allow of a free passage of the oil to the grooves without exposing them to being choked by the material being compressed.

To clean the plates G it is only necessary to remove the Wire-cloth coverings H, which may be speedily done, when the grooves 7c may be quickly wiped out.

' The wire-cloth plates or coverings H are important adjuncts, inasmuch as their meshes serve as an outlet for the oil directly downward, and from thence through the grooves 70, thus greatly reducing the power necessary to press out the oil as compared with forcing it out sidewise over the close or solid bottoms of 20' the pressingplates, as is usually done.

independent pressingplates Gin sets pendent the one from the other, for operation in rela- 3c tion with each other substantially as specified.
